My question is about #10 on the introdution to function families...The illumination y form a certian florescent bulb is given as a function of distance x by the generalized power functionfor p=-1 with A=370, h=0 and c=0. Determine the illumination at distance of 1, 2, 3, 4 units, and sketch a graph....I'm not sure how to sketch the graph useing units 1 ,2 ,3 and 4...Do I need to pluge 1-4 into x? The graph is rather hard to sketch because the numbers are so large... Thanks.

The generalized power function is y = A ( x - h)^p + k, so the function for p=-1 with A=370, h=0 and c=0 is

y = 370 ( x - 0) ^ -1 + 0, or just y = 370 x^-1.

So you just plug in x = 1, 2, 3 and 4, make a table of y vs. x and plot the graph.

If the numbers are large then you label your graph accordingly.
